We consider a 5-dimensional brane world model with a single brane closely related but distinct from the Randall-Sundrum brane model. In particular we focus on the localization of 5D fields with different spins – spin 0, spin 1/2, spin 1 – to the brane. We find that the brane model studied here has different (and in some cases superior) localization properties for fields/particles with...

The Renyi entropies and entanglement entropy of 1+1 CFTs with gravity duals can be computed by explicit construction of the bulk spacetimes dual to branched covers of the boundary geometry. At the classical level in the bulk this has recently been shown to reproduce the conjectured Ryu-Takayanagi formula for the holographic entanglement entropy. We study the one-loop bulk corrections to this...

2+1 dimensional gauge theories have been an important theoretical testing ground for new ideas that could potentially be used in 3+1D. After three decades, a good understanding of 2+1D non-Abelian gauge theories still seems out of reach. Many think that using link invariants of knot theory may lead to a better understanding of these theories. With this motivation, we study Chern-Simons(CS) +...

I will discuss constraints necessary for the consistency of certain 4d string compactifications which go beyond those necessary for vanilla anomaly cancellation. Most realizations of the standard model do not satisfy these constraints, motivating the addition of new electroweak multiplets which are often protected by symmetry. This provides a new theoretical motivation for WIMP dark matter...

We discuss two possible covariant generalizations of the Aharonov–Bohm effect – one expression in terms of the space–time line integral of the four-vector potential and the other expression in terms of the space–time “area” integral of the electric and magnetic fields written in terms of the Faraday2-form. These expressions allow one to calculate the Aharonov–Bohm effect for time-dependent...
